Puzzle 12
“We – A, B and C – each have some children. (i) A has at least one girl and twice as many boys as girls. (ii) B has at least one girl and three times as many boys as girls. (iii) C has at least one girl and three more boys than girls. (iv) When I tell you the number of children we have – a number less than 25 – you will know how many children I have, but not how many children each of the others has. Altogether we have……..” Who is the speaker and how many children does the speaker have? |

We don't know who the speaker is because they haven't told us how many children they have.

I think I got this worked out.I reckon the speaker is B, and B has 4 children. The total number of children is 14: A and C have 6 and 4 each or 3 and 7 each, but you can't tell which. Am I right? If so, I wasted a load of time on that. If not, I've completely wasted a load of time on that! |

I think mine is right because notice in the last paragraph it says "When I tell you...."Notice the keyword 'WHEN'. The person doesn't actually tell us. |
